Answer:
x = 5
Step-by-step explanation:
3x - 7 + 4x = 28
Combine like terms
7x -7 = 28
Add 7 to each side
7x - 7 +7 = 28+7
7x = 35
Divide each side by 7
7x/7 = 35/7
x = 5
Answer:
length enlarged by 10 ft
Step-by-step explanation:
Given:
Width = 11 ft
length = 22 ft
New area = 352 ft²
New length = 22 + x ft
Find:
Value of x
Computation:
(11)(22+x) = 352
242 + 11x = 352
11x = 110
x = 10
So, length enlarged by 10 ft
Hey there!
The distance around a circle is its circumference. We are given the radius of the circle. To find the circumference, we need to find the diameter and multiply it by pi. The diameter is twice the radius. We multiply our radius by two..
5*2=10
Then we multiply by 3.14
10*3.14=31.4
Therefore, we will need 31.4 feet of ribbing to go around the rug.
I hope this helps!
Scale 1/15
Scale = 1 : 15
Sketch shows: 3 by 4.5
Actual = (3*15) by (4.5 * 15) = 45 by 67.5
Actual = 45 feet by 67.5 feet.
Answer:
(3d+1)-(d-4)=Profit
Step-by-step explanation:
So what you do here is you take the price you sold the table for, and subtract it from the price you bought it for.
